“…In Europe, the Habitats Directive (92/43/EEC; http://ec.europa.eu/environment/nature/legislation/habitatsdirective/; accessed 13 Feb 2018) is the main instrument for the protection and restoration of coastal dune habitats, but a comprehensive and critically tested classification of dune vegetation, needed for effective conservation planning, is still missing. Several detailed phytosociological studies have been carried out, mostly within restricted regions (Braun‐Blanquet, Roussine, & Nègre, ; Danin & Solomeshch, ; Demartini, ; Eig, ; Géhu, ; Géhu & Biondi, ; Géhu & Géhu‐Frank, ; Iakushenko, Matchutadze, Tokaryuk, Solomakha, & Bolqvadze, ; Isermann, ; Korzhenevsky & Kvitnitskaya, ; Mayer, ; Morariu, ; Oberdorfer, ; Piotrowska, , ; Rivas‐Goday & Rivas‐Martínez, ; Šilc et al., ; Sýkora, Babalonas, & Papastergiadou, ; Vicherek, ). These contributions reveal conflicting views on the syntaxonomy of dune vegetation, which can be partially related to advances in knowledge (see, for instance, the evolution in the syntaxonomic schemes published by Braun‐Blanquet, ; Braun‐Blanquet & Tüxen, ; Westhoff, Dijk, & Passchier, ; Pignatti, ; Sissingh, ; Géhu, , ; Géhu, Biondi, Costa, & Géhu‐Frank, ; Brullo & Furnari, ; Géhu & Uslu, ; Brullo, Giusso del Galdo, Siracusa, & Spampinato, ; Rivas‐Martínez et al., ; Bardat et al., ; Biondi & Galdenzi, ; Mucina et al., ).…”
